Parents have a strong influence on young children's science learning. Factors such as parental education, interest, and child-directed speech influence how children perceive and engage with science. While the role of informal early learning settings in providing a space for parents and children to engage with science has been documented, the power…

Recent evolutions, such as pervasive networking and other enabling technologies, have been increasingly changing human life, knowledge acquisition, and the way works are performed and students learn. In this societal change, educational institutions must maintain their leading role. They have therefore embraced digitally enhanced learning to…

Despite a decline in popularity within US society, posters continue to hold a prominent place within middle and high school science classrooms. Teachers' demand is satisfied by governmental and non-profit science organizations that produce and disseminate posters as tangible products resulting from their research, and instruments to communicate…

This article presents a critical review and analysis of key studies that have been done in science education and other areas on the effects and effectiveness of using diagrams, graphs, photographs, illustrations, and concept maps as "adjunct visual aids" in the learning of scientific-technical content. It also summarizes and reviews those studies…

Despite years of formal education, approximately one-third of all undergraduate students still cannot explain the causes of the seasons. Student manipulation of a handheld model is one approach to teaching this concept; however, the large number of students in many introductory classes can dissuade instructors from utilizing this teaching…

The author suggests that there is a need to identify methods of effectively and efficiently enhancing communication in the lecture room, laboratory or in the out-of-class environment. The study reported concerns the development of suitable new systems which will enable the teacher of chemistry to (1) use projection television for brief periods…
